Kraftelektroniken
Kraftelektroniken, or power electronics, is the field of electrical engineering that deals with the conversion and control of electric power using electronic switching devices. In Swedish, the term kraftelektroniken denotes the same field. It encompasses the design, analysis, and implementation of circuits that transform electrical energy from one form to another with high efficiency and reliability. Common tasks include rectification, inversion, voltage and current regulation, and power conditioning for grids, transportation, and industry.
Key components include semiconductor switches such as MOSFETs, IGBTs, diodes, as well as inductors, capacitors, transformers,
Applications span consumer electronics power supplies, computers, electric vehicles, renewable energy interfaces (PV inverters, wind converters),
Historically, the field emerged in the mid‑20th century with thyristors and diodes and matured alongside advances
Ongoing research areas include advanced control methods, high‑efficiency topologies, multi‑level and modular converters, power quality, and
